[0002] The scissor feet are composed of inner and outer shears, and are a special keyboard key structure. They are widely used in modern electronic products, especially laptops and some mid-to-high-end desktop computer keyboards. After the scissor feet are formed and ejected by ordinary equipment, the boss may still be inserted in the slot. At this time, it needs to be demolded manually, which is time-consuming and labor-intensive, thus affecting the use effect of the equipment.

[0003] The prior art CN220179544U discloses a scissor-leg mold, comprising a rear mold, a main body, a front mold, an inclined ejector, a guide inclined hole, a convex column, a first guide column, a front mold main body, an elastic connecting member and an ejection portion. During the mold opening process, the main body is driven by the rear mold to move in a direction away from the front mold. During the process of the main body moving in a direction away from the front mold, the inclined ejector moves in a direction away from the injection hole under the guiding action of the guide inclined hole, and drives the convex column to exit the injection hole. The end of the first guide column close to the rear mold can pass through the front mold main body. When the end of the main body close to the rear mold abuts against the bottom wall of the first accommodating cavity, the main body moves to the extreme position. The elastic connecting member will be driven by the rear mold to undergo tensile deformation, and enable the rear mold to continue to move a certain distance in the direction away from the front mold, so that the molded part can completely avoid the inclined ejector. After the rear mold moves into place, the part can be ejected from the rear mold by the ejection portion for demoulding, thereby realizing automatic demoulding of the convex column, thereby improving the use effect of the equipment.
